While TOsk-Gal4-driven mycbp RNAi did not affect ovary morphology (Fig 9A), it dramatically reduced stage 14 oocyte production and egg laying compared to control RNAi (yRNAi) (Fig 9B and 9C), suggesting that mycbp is important for oogenesis beyond the germline cyst stage. Here, MYCBP is linked to cyst.
